List 600 AUTOfollowback users -_- following back via autoFollowBackTool.com within 2 hours

it's a new free service → autoFollowBackTool.com who AUTOfollowbacks within 2h and sends as an option a daily tweet
"followed x user via autoFollowBackTool.com " but it seems the posted number is not correct

expect →that some user will unfollow you → that some user with 2001 flwing can't autof.b.
→ gain ~450 loyal flwrs (if u don't unflw)

you can scrape yourself more users with tweetadder.co#_free but only ~25 new users/day

with this free trial software you can too follow up to 250

the list → http://min.us/massfollow -_- its a .txtfile with a preview

i updated the list → 1000 accs

the next step are 1500 accs in ~ 30days ( the search returns only ~ 25 new accs /day )

does anybody know a tool to check such a list for suspended accounts
